Wize ,
Sometimes it benefits us to look at things in different ways. We must be skinning the cat differently. I prefer to keep the narrow lobe centers and if necessary ,change the intake or exhaust duration slightly to make up for deficiency where necessary.
I personally don't buy in to the theory of tighter centers making an engine peakier because I have never seen it happen.
Certain other engine designs are exceptions as you noted.
It would be nice to sit down with you over a few golden sodas someday.

And since we are off topic,I have to wonder how many different cams Andyf tried and what they were as Ive never seen much said about them. Anyway,carry in and have fun with your new heads!
